I spearheaded the Turborepo monorepo migration, developed the React Native mobile app, reduced codebase complexity by 30% through shared modules, and streamlined workflows with Husky and commit lints. I also optimized infrastructure costs by implementing caching and request decoupling, enhanced security with 2FA and HMAC, and architected a unified observability strategy for logging and monitoring.
